REVOLUBLE FILIER-PIPE CONNECTION.

Specification of Letters Patent.

Patented Sept. 216, 1916.

Application led February 21, 1916. Serial No. 79,540.

To all whom t may concern:

Be it known that I, CHARLES E. MARTIN, a citizen of the United States of America, residing at Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Revoluble Filler Pipe Connections, of which the following is a specification.

This invention relates to a revoluble filler pipe connection for silos or the like.

The primary object of this invention is to provide a filler pipe connection for silos that can be easily and conveniently revolved around the body thereof to any point desired, so that connection can be made between the ller pipe connection and the filler Y l in the central opening of the silo roof one end of a filler pipe connection, the free end thereof being arranged and formed to travel around the body of the silo when rthe mounted end is rotated.`

A further object is to provide a means of rotatably mounting the filler pipe connection which also affords facilities for clamping the ends of the sections of the roof.

I attain these and other objects by the mechanism illustrated in the accompanying drawing, in which:

Figure 1 is an elevation of a fragment of a silo body, having a silo top mounted thereon, and a side elevation of the revoluble filler pipe connection showing it applied thereto. Fig. 2 is a sectional view of Fig. 1, taken on the line X X. Fig. 3 is a. sectional view of the filler pipe connection taken on the line 2-2 of Fig. 1. Fig. 4 is a vertical central section of Fig. 1 showing the assembly of the parts, a fragment of the silo roof, also two sections of the ensilage conductor pipe. Fig. 5 is a cross sectional view of Fig. 4 on the line 0.

In the drawings, reference numeral 1 represents a fragment of a silo body, 2 and 3 Y parts of a conventional SlO rOO. Part 3 is provided with a central opening 4 and a collar 5 havinga beaded upper portion 6 and a flanged lower portion 7 which extends overand around the upper ends of the sections forming a central opening in the part band ring 8 telescopes the inner per1phery--7 of the collar 5 and the flange 9 thereof is preferably made integral therewith, extending underneath and around the upper ends of the sections, forming a central opening in the part 3. Theupper ends of the sections forming the part 8 are interposed between the flanges 7 and 9 and the ianges and upper ends of the sections are clamped together holding the collar 5 and ring 8 in a vertical position with respect `to the part 3 of the silo. L shaped brackets 11 are fastened at predetermined points to the inner periphery of the ring 8 so as to leave their free bent ends extending inwardly toward the center of, the opening in thepart 3 of the silo roof. An angular ring 12 rests upon the free ends of the L shaped brackets; it is attached to and supported thereby preferably in a central position with reference to the opening in the part 3 of the silo roof. In order to rigidly support the angular ring l2, the L shape brackets are provided with braces 13 which are fastened to the part 3 of the silo roof and their free ends extend underneath and are secured to the free ends of the L shape brackets. Bolts secure the braces 13 to the band ring S at one end and the opposite ends 'of' the braces are secured by the bolt 10 to the free ends of bracket 11.

Vertical standards 14 aresecured to the inner periphery of the collar 5 and their lower ends are formed L shape and arranged and so located as to aline with the brackets 11, but spaced apart therefrom. A hood 15 having a central opening is mounted upon the upper portion of the standards and is provided with an upstanding flange 16 which surrounds the central opening. Bolts 17 pass through apertures in-the ends of the verticalV standards and the bracket 11, and when said bolts are manipulated to tighten them, the fianges 7 are drawn to and forced in frictional contact with the top of the ends of the sections forming the part 3 of the roof, and simultaneously therewith the flanges 9 are drawn to and forced in frictional contact with the bottom of the ends of the sections forming the part 3 of the silo roof, thereby securingr posed ends oi' the sections of the part 3 of the silo roof between said flanges and rigidly clamping the collar 5 and the band ring 8 together. The space 18 between the brackets 1l and the L shaped ends of the supports 1l permit of their adjustment toward each other to insure eflicient and rigid clamping contact or elect.

The filler pipe revoluble connection 19 is provided with an angular ring 20 which is preferably located and secured to the liller pipe connection at a point above the end 2l. The angular ring 20 rests upon and is supported upon the angular ring 12 thereby supporting for rotation the filler pipe cone nection 1 9 upon what might be aptly termed a turntable7 mechanism. The free open end 22 of the iiller pipe connection is arranged and formed to lie spaced apart from the exterior of the silo body. A flange coupling 23 is provided on the end of the filler pipe connection.

Reference numeral 24 represents a fragment of an ordinary filler pipe having a flange coupling 25 attached thereto, the op posite end (not shown) being Iadapted to be `connected to an ensilage cutter orthe like.

A sliding bracket shoe 26 is attached-to the free end 2l of the iller pipe connection and its feet 27 are adapted to slide around :the exterior of the silo'body maintaining the free .end of the filler pipe connection at a predetermined distance from the silo body as it is being revolved around said silo body. Braces 28 are provided to strengthen the liller pipe connection at the point where it is curved.

Reference numeral 30 represents sections of a conductor pipe.

The operation of the rotatable pipe filler `connection is as follows; to wit: vThe ensilage cutter or the like is vfirst located at a point around the silo that is the most accessible or easy to approach, the Yuser then mounts the ladder 29 and revolves the filler pipe connection. until it is in close proximity' to the ladder and convenient to the user; 4the filler ypipe 2l is then connected to the revoluble filler pipe connection through the medium oit' the flange couplings and ythe liller pipe connection carrying the liller pipe is then revolved to a point where it can be easily and conveniently attached to the ensilage cutter, thereby lobviating the necessity of using a separate ladder or providing a suitable place to erect it.

That is claimed is:

1.'In combination with a silo and a silo Copies of this patent may be obtained-for ve cents each, hyaddressingthe Commissioner of patents.

Vroof, a filler pipe connection, means to mount one end thereof for rotation over a central opening in the roof, the opposite end being arranged and adapted to travel around the silo when the mounted end of the filler pipe connection is revolved.

2. In combination., a silo, a silo roof provided with a central opening, a filler pipe connection, means to mount one end of the filler pipe for rotation in the central opening of the roof, the free portion vof the filler pipebeing formed so that its end will lie adjacent to, but spaced apart from the silo, and means to slidably maintain the free end of the filler pipe connection in spaced relation to the silo when it is revolved.

3. In a revoluble filler pipe for silos, a silo roof provided with a central opening, means ,to mount one end ofthe vfiller pipe for rotation in said opening the opposite end being bent to clear said roof and lie adjacent to the silo, andv means attached to said last mentioned end to slidably contact with the silo and maintain said end a predetermined distance from said `silo duringthe operation of rotating the mounted end of the filler pipe.

t. In a revoluble device for fillingV silos, asilo roofA having a central opening, a `ller pipe, a ring and means-to support same in said opening, a ring fitted adjacent to one end of the .filler `pipe and adapted to coperate ywith the vfirst mentioned ring to movably support said end for rotation in the` opening in the roof, means to slidably sup port the free end of the ller pipe spaced yapart from the exterior `of ,the silo.
